Photocurrent Imaging of Multi-Memristive Charge Density Wave Switching in Two-Dimensional 1T-TaS2

Tarun Patel, Junichi Okamoto, Tina Dekker +6

Transport studies of atomically thin 1T-TaS2 have demonstrated the presence of intermediate resistance states across the nearly commensurate (NC) to commensurate (C) charge density…

Revealing the site selective local electronic structure of Co $_{3}$ O $_{4}$ using $2 p 3 d$ resonant inelastic X-ray scattering

Ru-Pan Wang, Meng-Jie Huang, Atsushi Hariki +9

We investigate mixed-valence oxide Co $_{3}$ O $_{4}$ using Co $2 p 3 d$ resonant inelastic X-ray scattering (RIXS). By setting resonant edges at Co $^{2 +}$ and Co $^{3 +}$ ions, the $dd$ excit…

Strong localization of oxidized Co3+ state in cobalt-hexacyanoferrate

Hideharu Niwa, Masamitsu Takachi, Jun Okamoto +5

Secondary batteries are important energy storage devices for a mobile equipment, an electric car, and a large-scale energy storage. Nevertheless, variation of the local electronic…

Distinct surface and bulk charge density waves in ultrathin 1T-TaS2

Rui He, Junichi Okamoto, Zhipeng Ye +10

We employ low-frequency Raman spectroscopy to study the nearly commensurate (NC) to commensurate (C) charge density wave (CDW) transition in 1T-TaS2 ultrathin flakes protected from…
